Have you read Dan Brown's newest novel? Apocalyptic.
Even the big boys are taking their shot at the apocalypse. Inferno, by Dan Brown follows his formula pretty closely throughout, but what was exciting to parallel as I read it was that Brown's apocalyptic vision shares the same vision of that in The Judas Syndrome.
Perhaps you remember Earl's talk around the campfire, in The Judas Syndrome, quoting Malthus and his prediction that the human race would kill itself off? Earl envisioned either a third world war, plague or simply overpopulation as the end we can expect. War would purge the planet of many billions if it were nuclear, a plague can go on and on if no cure is found, but the most likely and perhaps unexpected end to out legacy on this planet is the Malthusian theory of simply outgrowing our ability to feed ourselves.
Brown's Inferno plays out one of the three possible ends Earl spoke of in The Judas Syndrome, The person or organization coined The Grim Reaper, in The Judas Syndrome, unleashes a devastating nuclear holocaust upon the word to control population. Pick up Dan Brown's Inferno to see how he decides to kill us off.
